C# 키보드 후킹

첨부파일 다운로드하고.. 솔루션에 추가시켜야함...

 

globalKeyboardHook.cs

using System.Runtime.InteropServices; using Utilities; //첨부cs파일 네임스페이스 namespace key_preview { public partial class Form1 : Form { globalKeyboardHook gkh = new globalKeyboardHook(); public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { gkh.HookedKeys.Add(Keys.Decimal);//후킹할 키 등록 gkh.KeyDown += new KeyEventHandler(gkh_KeyDown); //후킹된 키 이벤트 gkh.KeyUp += new KeyEventHandler(gkh_KeyUp); } void gkh_KeyUp(object sender, KeyEventArgs e) { e.Handled = true; } void gkh_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode.ToString() == "Decimal") { keybd_event((byte)Keys.D0, 0, 0, 0); // 'A' key down 키보드이벤트 만들기 keybd_event((byte)Keys.D0, 0, 0x02, 0); // 'A' key up ( 0x02 = KEYEVENTF_KEYUP ) keybd_event((byte)Keys.D0, 0, 0, 0); // 'A' key down keybd_event((byte)Keys.D0, 0, 0x02, 0); // 'A' key up ( 0x02 = KEYEVENTF_KEYUP ) keybd_event((byte)Keys.D0, 0, 0, 0); // 'A' key down keybd_event((byte)Keys.D0, 0, 0x02, 0); // 'A' key up ( 0x02 = KEYEVENTF_KEYUP ) } e.Handled = true; } [DllImport("user32.dll")] static extern uint keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

수정사항 : 

아래함수 수정 ->

public globalKeyboardHook() 

{

      GlobalKeyboardHook();

      //hook();

}

public void hook() 

{

      IntPtr hInstance = LoadLibrary("User32");

      hhook = SetWindowsHookEx(WH_KEYBOARD_LL, khp, hInstance, 0);

}

----------------------------------------------------------------------------------------------

아래함수 추가 ->

keyboardHookProc khp;

public void GlobalKeyboardHook() 

{

    khp = new keyboardHookProc(hookProc);

    hook();

}
